The invention contemplates novel features in a shaver head and isdirected more particularly to the shape characteristics of the combstructure and of the cutter. The cutter may be driven by any desiredtype of motor, one type of motor being shown in connection with theembodimentof Figs. 1 to inclusive, and another type of motor drive beingshown in connection with the embodiment of Figs. 11 to 17.

Referring first to the embodiment shown in Figs. 1 to 10, the numeral l8designates generally the handle of the shaver made in the form of ahousing for the purpose of enclosing the motor. The handle has a bodymember l9 and a cover 2| secured to the body by means of .screws 22 and23, in this instance arranged on the longitudinal center line. Securedwithin the handle is an impulse motor having the usual coil 24, fieldpole pieces 25, and armature 26. The armature 26 is supported in spacedplates 21 and carries a crank pin 28 arranged to drive the cutter in amanner presently to be described. Electric current is supplied to themotor through terminal posts 29 located in one end of the handle in theusual fashion.

Carried in the opposite end of the handle is a shaver head assemblydesignated generally by the numeral 3| which in this instance includes aframe in the form of a box-like structure havin a back wall 32 providedwith annularly disposed flanges on three sides forming a bottom wall 33and side walls 34, a plate 35 being secured to the spaced relation tothe ribs and maintaining thefree edges of the bottom and side walls asshown in Figs. 8 and 9 to complete the box-like frame structure. Theframe 3| is held in position in the handle by means of screws 36 and 31which also serve to hold the cover 35 in position against the walls33'and 34. One or more screws 38 act between the wall 32 in the case tofurther retain the frame in position.

A comb unit designated generally by the numeral 39 is also held in theframe 3| by means of the screws 36 and 31, as will be apparent fromFigs. 3 and 9 and may be removed as a unit from the'frame and from theshaver by removal of the screws 36 and 31. This comb unit includes atruss, a supporting structure and a skin-engaging structure seatedthereover, the truss structure in this instance comprising three ribsdesignated generally by the numerals 4|, 42 and 43 (Fig. 4), the ribshaving central arched supporting portions 44, 45 and 46 depending legs41, 46 and 49 at opposed ends thereof, each of these legs having anopening 5| adjacent the lower end thereof. Tubular rivets 52 passthrough the openings 5| of the legs,.one on each of the screws 36 and31.

Each of these rivets carries spacer sleeves 54 disposed between the legs41 and 46 and the legs 46 and 49 respectively, for the purpose ofspacing the distance between the ribs (Fig. 9) The rivets also carry endsleeves 55 and 56 at opposite ends thereof against which the rivets arepeened, these end sleeves having annular flanges 51 and 56 providingannular grooves 69 and 6| for a purpose presently to be described. Theskin-engaging structure comprises a central close shaving areadesignated generally by the numeral 62 and marginal areas indicated bythe numerals 63 and 64. In this instance the central area comprises astrip of thin sheet metal of substantially greater length than widthhaving substantially parallel side edges 65-and 66 intermediate its endsand having end portions 61 and 68 of somewhat greater width, the widthofthe strip being such that the side edges 65 and'66 can seatsubstantially along the center of the ribs 4| and 43 when the strip isseated thereon as shown. The strip is secured to the truss structure bymeans which will not cause distortion'of. the very. thin strip. In thepresent instance I employ wire retaining members 68 and H extendingtransversely of the strip at the widened portions 66 'and 61, passingthrough spaced openings in the strip, and depending therefrom as bestshown in Fig, 3. The depending ends of said wire members have loops [2and 13 which pass around the end sleeves 65 and 56 and seat in theannular grooves 59 and 6|, thereby drawing the strip taut against theupper edges of the ribs 4|, 42 and 43 without-distortion.

The marginal areas 63 and 64 include, in this instance, marginalportions of similar structure, each having depending parallelly disposedside portions 14 and top portions l5,having edges shaped to seat in edgeabutment against the edges 65 and 66 of the central strip, as best shownin Figs. 4 and 8. The side portions are secured against the legs 41 and48 of the ribs 4| and 43 by means of screws 16 and I1, spacer sleeves l8and I9 maintaining thev side portions in proper edges of the topportions 15in abutment with the edges 65 and 66 and, in seatedrelationship against the upper edges of the ribs 4| and 43. The sideportions 14 are curved to conform with the lengthwise and crosswisecurvature of the central portion 62 above described, and the marginalsides areformed in the nature of a cyma curve, as shown at 8| at thejunction between the side portions and the top so as tooverhang orproject over the side portions as best shown in, Figs. 8', 9 and 10. Theinner edges of the top portion 15 are rounded slightly as shown at 82 soas to merge with the outer surface of the central area. The marginalportions are preferably formed from sheet metal and suitably hardenedafter their formation to provide the desired edge retaining propertiesand to withstand the wear occasioned by the shearing action presently'to be described. Inthis particular instance said portions areapproximately ten-thousandth's of an inch in thickness. The top portionof the marginal area is provided with spaced U-shaped cuts as shown at(Fig. 10) whichlcuts extend downward beyond the overhanging portions 8|and provide outwardly disposed teeth 84, which teeth terminate at theirfree end slightly beyond the plane of the sides 14 and provide shearingedges along their sides. Shearing edges are also formedon opposed sidesof the slot 83 in the areas designated by the numerals 85 and 86 so thateach of the U-shaped slots functions to provide four shearing edges.These slots are spaced longitudinally of the marginal areas 63 and 64 asbest shown in Fig. 4 to provide clipping action on each side of the combextending throughout substantially the length thereof. The intermediateportions between the slots such as shown at 81 act as guards to limitthe approach of the teeth to the skin of the user. The projecting teeth64, while protected by the adjacent guards 61, serve to effectivelyengage beneath and pick up long hairs. 1 This function is facilitated bythe relatively wide mouth opposite the end of each tooth 64 and thenarrow siot-like areas 8586 aasaoss opening therefrom, with the resultthat I long hairs may enter the slotted area either lengthwise orcrosswise with respect to the cutting tooth 84 and be readily engagedbeneath the tooth or across the cutting edges at the outer side of theslotted areas diitii.

The strip forming the central area 52 is preferably formed of soft sheetsteel of thin cross section-in the region of three thousandths of aninch or less thickness. After having been formed to the desired shapethe strip is suitably hardened ,to provide proper edge-holdingproperties for the cutting edges at the inner end of the hairreceivingopenings and to withstand the shearing action. This central area isprovided with a plurality of hair-receiving openings designated in Fig.4 by the numeral 88. The specific size,

shape and arrangement of these-openings may vary to a considerabledegree, the size of the openings depending to some extent on thethickness of the comb and its degree of curvature. For instance, inFigs. 1 to 4 I have shown the openings 88 in the form of slots whichextend diagonally across the area in longitudinally spaced relation. InFigs. 5, 6 and 7 I have shown alternative forms, the form shown in Fig.5 having two rows of spaced slots, as indicated at 89 and 9|,

the slots being spaced on opposite sides of the rib 62 and the areabeing solid in the space over the rib. In Fig. 6 I have shown astructure which includes three rows of slots as shown at 92, Q3

and .94, and wherein the. truss structure employs four ribs instead ofthe three ribs heretofore described for lending additional supportacross the Width of the central strip. In Fig. 7 I have shown acentral'strip which is provided with a plurality of circular openings asshown at 95, the openings being spaced longitudinally and laterally ofthe strip. In each case the openings are adapted to receive the short-hair of thebeard in such a way that the hair projects through theopening in position to be severed by joint action of the strip and acutter, which will presently be described, without letting the skinthrough to cause irritation or cutting. These openingsare of a kindadapted for close shaving. It will be understood that the number of ribsprovided in the truss structure will vary depending upon the width ofthe central strip and the amount of support required in this area.

The portion of the structure formed by the central area 62 and themarginal areas 63 and N, which I have designated the skin-engagingportion of the comb, is arched in two directions at right angles to eachother. In other words, this skin-engaging portion is archedlongitudinally of the comb as shown inFig. 3 and is likewise archedtransversely as shown in Fig. 8, the central strip and the top portions15. being formed individually in such manner that when positioned on thetruss structure the composite top surface thus formed produces thearched skin-engaging portion, and this shape characteristic forms animportant partof the invention for the reason that by so forming thestrip an extremely thin section may be used having substantially greaterrigidity than is the case with a flat sheet. Another advantage is thefact that this curved surface greatly facilitates the shaving operationfor the reason that when pressed against the skin it imparts curvaturethereto tending to distribute the pressure and to cause the hair toenter the openings at the proper angle, and facilitates the entry of thehair into the openings. Another advantage is that by reason of itsdouble curvature and elongated form it is better adapted to follow thedifferent shapes of the face and to work into hollow portions. It willalso be noted that the marginal areas 63 and as are formed of metal ofsubstantially greater thickness than that of the central area 62 so thatthe marginal areas have materially greater strength and rigidity towithstand the greater forces occasioned by the clipping action, asdistinguished from the close shaving action, and likewise to preventbending and breaking of the teeth at out of their normal and trueposition due to mechanical damage.

In the preferred embodiment of my invention a flat cutter blade is usedin accordance with the principle covered in my Patent No. 2,081,694granted May 25, 1937. This blade coacts with the comb portions 62for'close shaving and the portions 63 and 66 for clipping long hairs.Any suitable orv preferred means maybe employed for oscillating thecutter blade at a high speed. The means used in the present embodimentare as follows:

Positioned in the walls Maud 35 of the frame 3| adjacent to the bottom33 thereof are bearings 96 and 91 adapted to support a shaft atextending through the frame, the shaft having a pin 99 to which isfixedly attached a crank arm I 6|. This arm is in the form of a forkhaving legs I02 and IE3 shaped to span the crank pin 28, as best shownin Fig. 2, whereby rotation of the crank pin swings the arm from side toside and causes the shaft 98 to oscillate. A sleeve wt has a press fiton the shaft 98 so as to be fixed thereon, and carries a pair of arms Eand Hit secured thereon in spaced relation by a spacer blocklt'l and byend blocks ms and its against which the ends of the sleeve i0 9 areriveted over to form a rigid permanent structure, as best shown in-Fig.8. The arms I05 and its project toward the comb and intermediate theirends are secured together by rivets Ill and a spacing block H2, whichspacing block carries a pin H3 serving as a guide for a spring H4. Thespring H4 also encircles a stem N5 of a cutter desig; natedgenerallybythe numeral H6. This cutter is formed of sheet metal and has a tongueI carrying the pin i i5 and seated between the arms I05 and 108 for freemovement longitudinally with respect thereto. Beyond the tonguev V IIIthe cutter flares outwardly as shownat M8 to a .width slightlyless thanthe distance between the side portions it of the comb, the end of thecutter being arcuate. as best shown in Fig. 8, to accurately seatagainst the inner surface of. the skin-engagingportion of the comb. Theenlarged portion H8 is received in slots-J i9 and IN in the ends of thearms I05 and IE6 in such fashion as to be capable of being freely urgedagainst the comb by action of the spring Hi, the fit being such as topermit of a minimum amount of lost motion between the cutter and thearms inthe direction of movement of the arms but to permit of a limitedamount of lateral movement so that the outer end of the cutter mayadjust itself laterally to the curvature of the skin-engaging portion ofthe comb. The cutter has a plurality of slots I22, I23 and I2 for thereception of the central portions 66, 45 and 46 of the ribs, these slotsbeing of such width as to permit of the lateral cutter moveportion fromend to end thereof, the outer end of the cutter moving in shearingrelationship to the shaving openings in the central portion 62 and inshearing relation with the teeth 84 of the marginal areas 63 and 53 toperform a clipping operation. During this oscillation the cutter isurged outwardly by the action of the spring H6 and also by action ofcentrifugal force due to the angular movement of the cutter. These twoforces cause the outer edge of the cutter to hug the inner surface ofthe comb and thus maintain a shearing pressure between these elements.Furthermore. the cutter is permitted to float laterally with respect tothe comb so as to. be held in intimate shearing coaction with the combthroughout the shearing stroke. For normal shaving operations on anormal beard the shaver is held so that the central area I52 into theplate I35 adjacent one edge thereof and carries a bearing M5, the screwpassing through the cover MI for mutual support, gaskets I46 beingdisposed between the bearing and the plate 535 and the cover MIrespectively, to prevent hairfrom passing out of the chamber I42 intothe lower part of the housing. The walls I38 and I39 likewise have feltgaskets I31 or the like extending from front to rear and seating againstthe cutter operating lever for sealing the chamber M2 from the motor.The bearing I45 has a depending fork comprising arms I48 disposed onopposite sides of the oscillating arm I34, whereby operation of themotor causes the bearing M to oscillate on the pin I44, Extendingupwardly from the bearing I45 are spaced arms contacts the'skin. Thecurvature. of this area. I

causes the skin to be arched so as to facilitate cutting of the hairvery close to the surface of the skin, and this is augmented by thethinness of the central area. Where thebeard is slightly longer thannormal so that the length of the hair interferes with its entry into theopenings of the central area, or when an occasional hair is encounteredon the face which either because .of its length, its diameter, or thedirection in which the hair lies, it is not readily sheared by thecentral area, the shaver is tilted slightly 'so as to bring one of themarginal areas 62 and 63 into contact with the skin, whereby either thehair of the longer beard or the individual hair is causedto be clippedby action of the teeth 85 and associated cutting edges spaced along themarginal areas. Also, in the same cutting stroke the close cuttingshaving area may be moved across-the same hairs for close shaving andthus perform a dual cutting function. As the hair is cut, a certainamount'of the severed hair will be carried out at the ends of the comb,but part of it 'will dro'p, down into the interior of the frame 3I.Openings I in the walls 32 and 35 of the frame and openings I26 in thehandle permit the discharge of this hair outward from the interior ofthe frame. In order to prevent access of the hair .to the motorstructure, the juncture between the frame and the handle is sealed bypacking rings I21 (Fig. 9).

In Figs. 11 to 17' inclusive, I have shown' a modified form of theinvention having the essential characteristics thereof but in which thespecific details vary from that heretofore de-- scribed. It will be seenfrom this disclosure that the invention may take a number of specificforms and be made in different ways, but yet incorporate the essentialcharacteristics of the invention. This form of the invention includes ahandle and motor housing comprising two interfitting sections designatedgenerally by the numerals I28 and I29 secured together by means ofscrews BI 'and I32. In this instance'the handle carries a vibratory typemotor designated I49 and I5! having slots I52 and I63 at their upper endfor the reception of a cutter designated generally by the numeral I54,the cutter having a depending tongue I55 disposed between the armsI49-I6I and a pin I56 adapted to seat in an opening I51 in the bearingI45, the tongue and pin having looseness of movement therein to acertain degree to permit longitudinal movement of the cutter outwardlyand to permit a certain amount of lateral movement. A spring I58 acts onthe shoulder between the tongue and the pin to normally urge the cutteroutward. The cutter is curved outwardly beyond the tongue I 55 as shownat I53 and has an arcuate outer edge I 6I, the cutter being analogous tothat of Fig. 8.

A comb unit separately shown in Figs. 13 to 15 inclusive. is seated inthe end of the housing in the manner shown in Figs. 11 and 12. This vcomb includes a truss structure having tubular rivets designatedgenerally by the numerals I62 and I63 upon which is seated spacingsleeves I64 generally by the numeral I33 adapted to producereciprocation of an arm I34, this motor, and

' its application to a shaver being subject matter of an application forpatent by Ivar Jepson, Ser. No. 324,599 filed March 18, 1910. A plateI35 is secured'in the housing portion I28 by meansof screws I36 and I31and has formed thereon upstanding wall I38 and I39 against the freeedges of which seat a wall or cover I 4| forming a chamber I42 havingthe upper edge thereof open, as shown in Fig. 12, the cover beingsecured in position by screws I 43, A pin I44 is threaded to m (Fig.13), 'a rib I68 having a central portion I69, and depending arm "I andI12 are supported on the rivets I62 and I63, the arms having openingsfor the reception of the rivets and being retained thereon by thespacing blocks as best shown in Fig. 15. The comb has a facing structureincluding a central shaving area I13 and marginal clipping areas I14 andI 16 (Figs. 13 and 15). This face structure is formed of two faceportions having the form shown in Fig. 16 including a side I16 and a topI11, the sides of each surface portion being provided with openings I18for reception on the ends of the rivets I62, the sides being securedbetween the spacing sleeves and the outwardly disposed ends of therivets, as best shown in Fig; 15, to form a rigid surface structure,which unit may be inserted in and removed from the shaver as a unit. Thesides I16 are thus secured in approximate parallel relationship with thetop portion I11 disposed inwardly. The top portions are or such widththat the free edges I18 thereof abut in the area over the rib I66, andthe space relationship is such that these edges are pressed firmlytogether to thus form the skin-engaging surface comprising the centralarea I13 and the marginal areas-I14 and I15. At the Junction between theside I16 and the top I11 the metal is curved outwardly as shown at I8Iso as to overhang the sides. This area is provided with a plurality ofU-shaped slot-like openings as shown at I82 disposed longitudinally ofthe top and providing longitudinally disposed teeth I83, the

slots I82 and teeth I 83 being analogous in form and function to theslots 83 and teeth 84 heretofore described. The top is also providedwith I18 are brought into engagement, the slot I 88 of the two portionsmeet so as to produce a structure shown in Fig. 13. In Fig. 1'1 I haveshown slots I84 of the twoportions staggered so that the teeth I85 ofone portion meet the slots I84 of the other portion. This ha theadvantage that when the shaver is moved over the skin, all parts of theskin between the end teeth of the central portion are covered by theslots with the consequent increase in the probability that all of thehair will enter the slots during a single pass of the shaver over theskin.

The comb is held in position in the shaver by mean of screws I86 and I81which pass through the tubular rivets I62 and I63 and are threaded intothe plate I35. The cover II has openings, not shown, through which theheads of the screws I88 and I81 pass. The shaving endsof the housingportions I28 and I28 converge inwardly as shown at I88 and I88 (Fig.12), 502.5 to seat against the sides I16'of the comb to enclose thelower portions of the comb and prevent the access of hair to theinterior of the motor chamber.

The cutter I14 reciprocates over the inner surface of the skin-engagingportion of the comb in the same manner as described for the cutter I I6and has a similar type of laterally floating action, permitting it tofollow the curvature of this portion of the comb. The cutter is alsoprovided with a slot I8 I for reception of the central portion I68 ofthe rib and has 'a certain amount of freedom for lateral movement withrespect thereto.

As in the previous embodiment the skin-ene gaging portion of the combformed by the two top parts III is arched transversely of its length andlongitudinally of its length as will be seen from a comparison of Figs.14 and 15. In order to produce the desired characteristics in theskin-engaging portion of the comb, the tops of the surface structure arereduced in cross section in the central area I18. One satisfactory wayof accomplishing this is to grind the comb on an arc of substantiallygreater radius than the transverse arc of the remainder of the combportion, as for example, on an arc indicated by the line designated I82in Fig. 15. By so doing the cross section of the central area I13 isreduced while the cross section of the marginal areas'l14 and I15 isretained at its original thickness. It will be understood that the facestructure of the comb is preferably formed from sheet metal of suchthickness as to give rigidity thereto, and to give sufficient rigidityto the teeth I83 to prevent them from being bent out of shape inordinarythan with the previously described structure.

In the embodiment of my invention as shown in Figs. 18, 19 and 20, Iform the entire comb unit of a single piece of sheet metal to a shapesubstantially as shown in the blank, Fig. 18. Here the shaving area isindicated by the dotted lines I83. Within this area the hair-receivingopenings may be of any suitable or preferred size, shape or arrangement.However, in this species of my invention I prefer to employ two rows ofnarrow slots I 84 substantially in herring-bone arrangement and adaptedby reason of the shape to which they are subsequently formed, to providefor both close shaving and for snaring long hairs. The blank is thenformed to the shape substantially as shown in Figs. 19 and 20. Here itwill be observed that the skin-engaging portion for the side portions,although the general curvature of the comb both lengthwise and crosswiseserves in itself. to provide rigidity. The depending legs I88 serve forattaching the comb unit to the shaver housing or suitable supportingmeans substantially in the manner above described.

In Figs. 21 to 24 inclusive, I have shown another modification of myinvention in which the comb unit is composed of a single strip of metaldesignated'generally by 28I forming the skin-engaging part and trussstructure designated generally by 202 which may be in keeping with anyof the truss structures described. In this embodiment the comb memmberis provided with a centrally disposed close shaving area 203 havinghair-receiving openings of the kind described is formed and hardenedsubstantially as above described to provide a double archedconfiguration, that is, the curvature lengthwise and vcrosswise. Thecomb member may be secured to the truss structure by any suitable orpreferred means, such for example by riveting at the end portions beyondthe close shaving area 283. In Fig. 21 is shown openings 205 in the combmember for the reception of rivet elements 285 formed on the top of thetruss member 206 and adapted to enter the openings 205 and be peened orriveted over said member substantially as shown in Fig.23. It will beobserved that the rivet 205' isjpeened over only the outermost end ofthe opening 285 and in such manner as to hold the comb member 2III tautagainst the top of the truss member 286, as claimed in my applicationfor shaving implement, Ser. No. 200,899.

As in some of the embodiments above described, the thin skin-engagingmember is seated throughout the length of the shaving area or closelycontiguous thereto against upper surfaces of the truss structure. In theprevious instances, the comb supporting surfaces may beaccuratelyfinished as to curvature and the thin the full length of the comb, asshown in Fig. 22,

' these guards serving with the comb member to guide the skin andprevent it from entering into contact with the cutter.

In view of the foregoing disclosure it will be manifest that variousmodifications may be made in the application of my invention withoutdeparting from the spirit and scope thereof, and I desire, therefore,should be placed thereonas are imposed by the prior art and the appendedclaims, in which I claim:
